Answer:
To have maximum profit, the price must be increased by 5,
Step-by-step explanation:
Given that the price increase function is:
f(x) = -2x² + 20x + 150,
For maximum profit, then f(x) = 0.
Putting f(x) = 0, we have
-2x² + 20x + 150 = 0
Or
x² - 10x - 75 = 0
(x + 5)(x - 15) = 0
x = -5
Or
x = 15
Again, differentiating f(x) and equating to zero, we have
-4x + 20 = 0
4x = 20
x = 20/4
= 5
To have maximum profit, the price must be increased by 5,
It is just less
because 8.3 is 83 and
84 tenths is 84
so 83<84
So z-4 2/3=2 2/3
so 4 2/3=12/3+2/3=14/3
2 2/3=6/3+2/3=8/3
z-14/3=8/3
multiply both sides by 3
3z-14=8
add 14 to both sides
3z=22
divide both sides by 3
z=22/3=7 1/3

Answer:
part A: 3yx
Part B: (x+y)+z
C: 3xy-6x
Step-by-step explanation:
Commutative property: change the orders in which numbers are multiplied
associative: when all the integers are in addition you can add parentheses wherever u like
distributive: multiply the number just outside the parentheses with the every numbers inside the parentheses
Hope this heps!
